Actually, pkcs11-helper and p11-kit checks also depends on pkg-config ... the systemd pkg-config calls just happens to be run first to bail out if it can't figure out the systemd details. It seems pkg-config first called on pkcs11-helper, then openssl - both which considers "failure" as non-critical. If it is only the openssl.pc missing on some *BSD distros, then I think we can have pkg-config being a requirement which is checked for as early as possible. Otherwise, we'll need to check for pkg-config if pkcs11-helper, p11-kit or systemd is enabled. And for each new dependency with pkg-config support. Btw ... I also see we could utilize pkg-config for lz4 too (at least with lz4-1.7.3) -- kind regards, David Sommerseth OpenVPN Technologies, Inc
